Optical disk drive

ABSTRACT

An optical disk drive includes a main body and a tray. The main body includes a housing, a first resisting member, and two rails. The first resisting member and the two rails are disposed in the housing. The tray is slidably coupled to the two rails, and is operable to be switched between a first state and a second state. The tray is received in the housing in the first state, and protrudes out of the housing in the second state. The tray includes a second resisting member, which is capable of being elastically compressed along a resisting direction substantially perpendicular to a sliding direction of the tray. The second resisting member is resisted by the first resisting member along the resisting direction to secure the tray in the first state. The second resisting member is away from the first resisting member in the second state.

BACKGROUND

1. Technical Field

The present disclosure relates to optical pick-up devices, and particularly to an optical disk drive capable of tightly securing a tray.

2. Description of Related Art

An optical disk drive usually includes a main body and a tray slidably coupled to the main body. The main body includes two rails for allowing the tray to slide therein. To decrease resistance between the tray and the rails when the tray is sliding in or out, the tray is usually spaced a distance away from the rails. Thus, when the optical disk drive reads or writes to a spinning optical disk, the vibration of the tray caused by the play between the tray and the rails may lead to erroneous data being read from or written to the disk.

Therefore, it is desirable to provide an optical disk drive capable of tightly securing a tray, which can overcome the above-mentioned problems.

DETAILED DESCRIPTION

Embodiments of the present disclosure will now be described in detail with reference to the drawings.

Referring to FIGS. 1 and 2, an optical disk drive (ODD) 100 in accordance with an exemplary embodiment is illustrated. In the embodiment, the optical disk drive 100 may be a slim type version, particularly employed in a laptop computer (not shown). The ODD 100 includes a main body 10 and a tray 20 slidably coupled to the main body 10. The tray 20 is adapted to receive an optical disk (not shown). When the tray 20 is completely received in the main body 10, the disk drive 100 is operable to drive the optical disk.

The main body 10 includes a housing 11, a first rail 13, and a second rail 14. The housing 11 includes a bottom plate 114 and three sidewalls 115, 116, 117 extending upright from three edges of the bottom plate 114 respectively. The sidewall 115 is substantially parallel to the sidewall 116. The sidewall 117 is substantially perpendicularly connected between the sidewalls 115 and 116. The housing 11 defines a receiving space 118 bounded by the sidewalls 115, 116 and 117. The first rail 13 and the second rail 14 are slidably disposed in the housing 11 and connected to the sidewalls 115, 116 respectively. The first rail 13 is substantially parallel to the second rail 14. The first rail 13 and the second rail 14 are operable to slide along a first direction D1 to be completely received in the housing 11 and along a second direction D2 to partially protrude out of the housing 11. The first direction D1 is opposite to the second direction D2.

The second rail 14 includes a first resisting member 141 formed on one end of the second rail 14 adjacent to the sidewall 117. The first resisting member 141 includes a resisting surface 145 and a guiding surface 143 (shown in FIG. 4). The resisting surface 145 is positioned away from the sidewall 116 and substantially parallel to the first direction D1. The guiding surface 143 is connected to one end of the resisting surface 145 away from the sidewall 117. The guiding surface 143 is inclined with respect to the resisting surface 145, and forms an acute angle with the second direction D2.

The tray 20 includes two opposite side surfaces 21 and 22. The side surfaces 21 and 22 face the first rail 13 and the second rail 14 respectively. The tray 20 further includes two elongated slide bars 24 formed on the side surfaces 21 and 22 respectively. The slide bars 24 are substantially parallel to the first rail 13 and the second rail 14. The slide bars 24 are slidably connected to the first rail 13 and the second rail 14 respectively, such that the tray 20 is slidable with respect to the main body 10.

Referring to FIG. 3, the tray 20 defines a concave space 221 in the side surface 22 adjacent to one end of the tray 20 towards the sidewall 117 of the housing 11. The tray 20 includes a second resisting member 26 suspended in the space 221. The second resisting member 26 includes a cantilever beam 261, a spring portion 262, and a resisting portion 263.

One end of the cantilever beam 261 is fixed to the tray 20, such that the cantilever beam 261 extends into and is suspended in the space 221. The cantilever beam 261 is substantially parallel to the slide bar 24, and is elastically deformable towards the space 221. The spring portion 262 is a winding sheet connected to a distal end of the cantilever beam 261. In this embodiment, the spring portion 262 includes a first spacing portion 264, a second spacing portion 265, a first beam 266, and a second beam 267. The first spacing portion 264 extends upright from the distal end of the cantilever beam 261. The first beam 266 connects to the first spacing portion 264 and is suspended over the cantilever beam 261. The second spacing portion 265 extends upright from one end of the first beam 266 away from the first spacing portion 264. The second beam 267 connects to the second spacing portion 265 and is suspended over the first beam 266. The first beam 266 and the second beam 267 are substantially parallel to and deformable toward the cantilever beam 261. As such, the spring portion 262 can be elastically compressed. The resisting portion 263 is connected to a distal end of the second beam 267 away from the cantilever beam 261 and protrudes out of the space 221.

When the tray 20 slides along the first direction D1 (FIG. 4) to be received in the housing 11, the guiding surface 143 is adapted to guide the resisting portion 263 to the resisting surface 145. When the tray 20 is completely received in the housing 11 (the first state), the resisting portion 263 is pressed by the resisting surface 145, thus the spring portion 262 is compressed and the cantilever beam 261 is elastically deformed towards the space 221 accordingly. Therefore, the first resisting member 141 applies a resisting force to the second resisting member 26 so as to tightly secure the tray 20. The direction D3 of the resisting force is substantially perpendicular to the first direction D1 and the second direction D2. Thereby, vibration of the tray 20 during use can be decreased due to the resisting force.

Referring to FIGS. 5 and 6, when the tray 20 slides a predetermined distance along the second direction D2 to be in the second state, the second resisting member 26 departs from the first resisting member 141 and is spaced a distance away from the second rail 14. As such, a resistance to movement of the tray 20 is decreased.

In other embodiments, the second resisting member 26 can be disposed on the main body 10, and the first resisting member 141 can be disposed on the tray 20 correspondingly. Alternatively, two second resisting members 26 can be mounted on both the side surfaces 21 and 22. Correspondingly, the first resisting members 141 can be mounted on both the first rail 13 and the second rail 14.

Additionally, the first rail 13 and the second rail 14 do not necessarily need to be slidable with respect to the housing 11. Alternatively, the first rail 13 and the second rail 14 can be fixed to the housing 11.

Furthermore, the cantilever beam 261 can be omitted in other embodiments. Correspondingly, the spring portion 262 is fixed to the tray 20.

While various exemplary and preferred embodiments have been described, it is to be understood that the disclosure is not limited thereto. To the contrary, various modifications and similar arrangements (as would be apparent to those skilled in the art) are intended to also be covered.
